máquina e processo para renovação de uma via

摘要

A machine for renovating a track includes the following: a transverse chain segment of an excavating chain is designed shorter than a crosstie length of new crossties. A ballast plow is disposed relative to a longitudinal machine axis between the transverse chain segment of the excavating chain and the device for placing the new crossties. A width-extending normal to the longitudinal machine axis-of the ballast plow is designed greater than the crosstie length of the new crossties.
